Abstract

The invention discloses a raw silk soft and anti-wear cutting fluid which comprises the following raw materials by weight: 4 to 6 parts of sodium molybdate, 0.5 to 1 part of laurocapram, 0.1 to 0.2 part of aluminum ammonium sulfate, 0.6 to 2 parts of diazolidinyl urea, 0.1 to 0.2 part of ricinus oil polyoxyethylene ether, 0.7 to 1 part of 2,6-butylated hydroxytoluene, 5 to 7 parts of acetylated lanolin, 3 to 4 parts of polylactic acid, 16 to 20 parts of dimethyl sulfoxide, 4 to 5 parts of raw silk, 20 to 30 parts of triethanolamine borate, 1 to 2 parts of sodium dodecyl sulfonate, and 200 to 300 parts of deionized water. A fibroin lubricating liquid (an intermediate product of the raw silk soft and anti-wear cutting fluid) takes natural silk as a main material, thereby being nontoxic, free of pollution, and high in lubricity; triethanolamine borate, which is excellent in extreme pressure lubricity, rust-proof, anti-bacterial, capable of sterilizing and the like, is mixed with the fibroin lubricating liquid to obtain a liquid mixture; the liquid mixture is modified with polylactic acid. Therefore, the fracture strength and wettability of a blend membrane can be improved.

A preparation method for the soft wear-resistant cutting fluid of raw silk, comprises the following steps:

(1) poly(lactic acid) is joined in dimethyl sulfoxide (DMSO), obtain PLA solution;

(2) above-mentioned raw silk is joined in the sodium carbonate solution of its weight 90-100 0.4-0.6wt% doubly, heat-insulation soaking 60-80 minute at 98-100 DEG C, filter, dry, wear into fine powder, mix with sodium laurylsulfonate, add the 85-90% of above-mentioned deionized water weight, stir, obtain fibroin lubricating fluid;

(3) Triethanolamine borate is heated to 80-90 DEG C, add PLA solution, fibroin lubricating fluid, magnetic stirring apparatus stirs 3-4 minute, adds Modulan, insulated and stirred 2-3 minute at 40-45 DEG C, obtains extreme pressure lubricating liquid;

(4) castor oil polyoxyethylene ether is joined in remaining deionized water, stir, add Sodium orthomolybdate, obtain rust protection liquid;

(5) mixed with rust protection liquid by above-mentioned extreme pressure lubricating liquid, be heated to 60-70 DEG C, 80-100 rev/min of dispersed with stirring 20-30 minute, add each raw material of residue, 600-1000 rev/min of dispersed with stirring 30-40 minute, obtains described cutting fluid.

Advantage of the present invention is:

Fibroin lubricating fluid of the present invention take silk as major ingredient, nontoxic pollution-free, oilness is high, the extreme boundary lubrication of Triethanolamine borate is good, and has the functions such as antirust, antibacterial, virus killing concurrently, mixes with silk fibroin solution, and adopt polylactic acid modified, breaking tenacity and the wettability of blend film can be improved, more stable lubricant film layer can be generated on the surface at frictional metal, effectively raise extreme pressure anti-wear and reactive behavior.

The Modulan that the present invention adds can the flexibility of modification cutting fluid, better promotes the effect of extreme-pressure anti-wear.
